Concrete Pipe Facts | General | General

Concrete pipe is a rigid pipe system that relies mostly on the strength of the pipe and is only slightly dependent on the strength derived from the soil envelope. The inherent strength of concrete pipe can compensate for site problems not designed for such as construction shortcomings and higher fill heights and trench depths.
